LOL ! STOCK Silvia S15 out class DC5 in looks,maybe debatable since looks are based on personal preference.BUT,out class in performance is NOT true.I have tested with a few stock and mildly modded S15 before,and my EK out class them in EVERY gear (except first gear we move side by side,but the moment 2nd gear engage,my car jump in front of him about half a car and slowly pull away).However,my EK is not stock.But its a more than fair comparison since its a 2.0 Turbo vs a 1.8 NA.In fact,a Putra with stock GSR (TD04) has more Gforce compared to a stock silvia S15.
So if my newbie 1.8 can whack a stock S15,i am very confident even a K20A can smoke a silvia without any problems.Although DC5 is heavier than a EK,the I-Vtec 2.0 engine makes up for it.The amount of money you need to spend to make a Silvia fast,is enough for a K20A turbo..and its smelling smoke for the Silvia all over again.
